A Correct answer
Explanation

A card is either red or black. The probability of drawing a red or black card is 1, as every card in a standard deck is one of these two colors. This is a sure event.

AI explanation

A standard deck contains 52 cards, of which exactly 26 are red and 26 are black, meaning every single card falls into one of these two categories. The probability of drawing a red card or a black card is therefore 52/52, which equals 1. An event with a probability of 1 is classified as a sure event, meaning it is guaranteed to happen.
